, and useful Improvements in Carpet Beatengaging elements.

ers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a This invention relates to an improved carpet beater of the type having carpet beating elements and one object of the invention is to provide improved means for mounting and actuating the boaters, the actuating means being so constructed that the heaters will be lifted and then released and permitted to drop of their own weight into striking engagement with a carpet placed upon a supporting table beneath the boaters.

Another object of the invention is to so construct the operating means for the beaters that the beater engaging elements .may

be held in an operative pos tion by resilient means and moved to release the beaters by cam means which will move the beater .en-

gaging elements to an inoperative position against the action of the resilient means, holding them in an operative position.

Another object of the invention is to so construct the-device that the heaters may be loosely mounted upon a shaft carrying the beater engaging means and thus the shaft for each beater serves not only as means for pivot'ally mounting the beater but also as means for rotatably mounting the .beater Another object of the invention is to provide an improved carpet beater in which the heaters may be movably mounted in a housabove a perforated carpet carrying table beneath which willbe positioned a fan for drawing the-loosened dirt and dust out of the carpet. p

Anotherobject of the invention is to so construct this carpet beating machine that the beater elementsnl'ay be mounted upon shafts at opposite sides of the machine, the two shaiits carrying the beaters and actuatin-g elements thereof, being driven from a common drive shaft extending beneath the v receptacle or body and having geared connection with the fan positioned beneath the carpet carrying table. I

Another object of the'invention is to provide a carpet beater which will'be-comparatively simple in construction and very efiident in operation.- V

This inventionis illustrated in the accompanying: drawings, wherein:

This improved carpet beatingmachine is provided with receptacle or body 1 which be provided with a cover if-desired and is supported upon supporting legsor-standards 2, the'supporting legs being connected by bars 3 wh ch-extend beneath the receptaic'le l in crossed relation as shown in Fig. 4 anduearry a cage or frame l which isheld in place by bolts 5 and 6; This cage in of a construction clearly shown in Figs. 3 and '4: and is provided with a lower plate 7 having arms 8 through which the bolts 5 pass and an upper plate 9 connected with the bottom of the receptacle by the bolts 6 and connected with the lower plate 7 the standards 10. The cage4 fills the space between the cross bars 3 and the bottom of the receptacle and thus provides a brace for the central portion of the receptacle as well as providing a gear housing in which will be positioned the gears 12, 18 and. 14. The gear 12 is carried by a vertically disposed shaft 15 which is'journalled in thebottom of the receptacle and has its upper end portion within the receptacle carrying {a fan 16. Thegears 13 and 14 are carriedby the shafts 17 and .18 which have their inner end portions mounted in bearings 19 carried by'the frame 4. The shafts 17 and 18 extend outwardly and each carries a pulley wheel 20, the shaft 17 in addition to its pulley 20, carries a pulley 21 about which will pass a belt 22 leading from a suitable source of power so that the shaft 17 may be rotated.

Within the housing or receptacle is placed. a table or carpet carrying element 23 having a top 24: which is perforated and preferably formed of woven wire fabric as shown in 3. Shafts 25 are rotatably mounted in bearings 26 and extend longitudinally of the receptacle adjacent opposite walls. thereof and above the carpet carrying table 23. Eachof these shafts 25 has one end portion extending through the adjacent end wall of the receptacle and upon the outer end portion of each shaft is mounted a pulley wheel 27 so that rotary movement can be trans- 'mitted to these shafts by the means of belts 23'which' pass about the pulley wheels 20 and pulley wheels 27. A beater board 29 is connected with each of the shafts 25 by hearing plates 30 and 3]., the bearings of these plates fitting. loosely upon the shaft so that the beater board may swing freely upon the shaft. Each of these boards is formed of thin material and will be provided with openings 32 for the sake of lightness and to permit the boards to swing freely without their action being interfered with by air resistance. It will thus be seen that the beater boards will have movement independent of the shafts 25 and that these boards may be swung upwardly and then released and may.

drop back to strike the carpet which will be placed upon the table 23 by their own weight.

In order to swing the beater boards upwardly, the bearing plate 31 of each board is provided with a finger extension 33 which constitutes an abutm'ent finger for engagement by the hook or pawl 34 which is pivo tally connected with the disk 35 by means of a bolt or other suitable pivot fastener 36.

This disk 35 is rigid upon the shaft 25 and 1 therefore as the shaft and disk rotate, the

hooked end of the pawl will be brought into engagement with the abutment finger 33 once for each revolution of the shaft. This pawl; is yieldably held in an extended or operative position by means of the springs 37 and is limited, in its outward movement through engagement with the block 38 heel portion of the pawl extends beyond the periphery of the disk and is'curved longitudinally thus providing a cam surface so for engagement by the cam 41 which is in the form of a bracket secured tothe wall of the a receptacle by a bolt or othersimilar fastener fi From a comparison- 9f Figs. 6 and 7 it will be readilyseen that as the shaft 25 rotates, the hook or pawl will first engage the finger 33 and cause the beater board to be swung upwardly. The cam extension of the pawl will then come in contact with the cam 41 as shown in Fig. 7 and as the shaft continues to rotate, this paw]. will be forced inwardly against the action of the spring 37 thus moving the pawl or hook out of en gagement with the finger 33 and releasing the beater board so that the beater board may fall back of its own weight and strike against the carpet which will be placed upon the table 23. As soon as the pawl or hook moves out of engagement with the cam 41, the spring will return the pawl to the extended position shown in Fig. 8 and the pawl will again be in position for engaging the abutment finger of. the beaterboard. The fan which is rotated from the shaft 17 by means of the cooperating gears 12 and 13 will rotate beneaththe table and cause a draft so as to remove the dirt and dust from the carpet. If desired, springs may be connected with the beater boards so that they may be pulled down into the striking position of Fig. 3 when released.
